Edit UVs in Polygon Proxy Mode

You can choose to create and edit UVs in either Polygon Proxy Mode or Standard Mode.

When you use Polygon Proxy Mode, you have more UV editing features available. However, because the UVs apply to the base mesh faces, textures might appear twisted, especially in areas that are significantly more refined than the base mesh. Editing UVs in Standard Mode (the default) ensures the best visual results for textures.

To use UVs from polygon proxy mode

1. Switch to Polygon Proxy Mode (right click the subdivision surface and choose Polygon).
2. Show the attribute editor and click the polyToSubdiv tab.
3. Set the UV treatment attribute:
   • To use the UVs from standard mode, choose Keep Subd UVs.
   • To use UVs you edit while in polygon proxy mode, choose Inherit UVs from Poly. The UVs will be copied back to the surface when you exit polygon proxy mode.
   • To not have UVs on this surface at all, choose No UVs on Subd. This removes any existing UVs on the surface.

The UV treatment attribute defaults back to Keep Subd UVs if you switch to Standard Mode and then switch back to Polygon Proxy Mode. If you want to edit UVs in polygon proxy mode again, you will need to change the UV treatment attribute again.
